  • IR Remote Control Transmitter
    . The infrared spectrum provides less ambient noise than other spectrums of light, like visible PHILIPS RC5 PROTOCOL light, and this makes infrared ideal for inexpensive reliable communication. The RC5 protocol is a common IR transmission proto- To create an IR control link, one needs a transmitter
  • Medical Device Link .
    20 companies, some of which have integrated the CAN module with a microcontroller. Because CAN is a data-link-layer protocol, it specifies only basic communication services. Users must specify an application layer and a communication profile, which defines the use of identifiers, configuration
  • Wireless control gets a highpriority
    New wireless LANs handle real-time audio and video through methods that may come in handy for factory networks. World's fastest I/O node? Visible (bottom) mounted on the wheel well of the Our Team Pontiac is the Opto 22 SNAP I/O rack holding a wireless link. The I/O system beams back data about
  • FieldServers Link Multiple Systems and Buildings at University of Arizona
    , Manager of Integrated Systems Group for the University of Arizona, was interested in the FieldServer not only to integrate the energy meters into the campus SCADA (Supervisory Control and Data Acquisition). The University utilizes BACnet as their campus-wide building automation communications protocol
  • A CAN Physical Layer Discussion
    layers) are not defined by the CAN specification. These other layers can either be defined by the system designer, or they can be implemented using existing non-proprietary Higher Layer Protocols (HLPs) and physical layers. The Data Link Layer is defined by the CAN specification. The Logical Link Control
  • Talk this way
    and unsuited for long distances. There is a wide choice of serial protocols, including several encoder-specific buses and a number of general-purpose industrial buses. The choice of protocols often depends on whether position data passes over a control network, the need for open communication
  • Ethernet Theory of Operation
    controllers. * Public data acquisition (date/time, stock quotes, Ethernet technology contains acronyms and terms news releases, etc.) defined in Table 1. THEORY OF OPERATION APPLICATIONS Ethernet is a data link and physical layer protocol Ethernet is an asynchronous Carrier Sense Multiple defined
